What is the primary function of binders in tablets?

• A. They act as flavoring agents
• B. They color the tablet
• C. Binders cement the active and inert components of tablets together to maintain cohesive portions
• D. They are fillers

Answer: (C)

Binders act as the cement that holds the active drug and all other ingredients together, forming a cohesive mass that stays intact during handling, packaging, and storage. They ensure the powder blend binds well during granulation and compression, producing a tablet with sufficient hardness and cohesiveness. While binders can influence how the tablet disintegrates and releases the drug, their primary function is to cement the components into a single, durable unit. Flavoring agents alter taste, colorants add color, and fillers simply add bulk, but they don’t provide the primary cohesion that binders deliver.
